The Knicks have replaced Scott O’Neil with former Mets executive Dave Howard as the MSG sports president, the team announced Monday.

O’Neil resigned over the summer after he and Knicks owner James Dolan had grown weary of each other. Sources said former Knicks president Donnie Walsh thought O’Neil became too intrusive in the basketball operations when the genesis of the job is marketing and business with the Knicks and Rangers and the arena’s other sports projects.

Dolan apparently felt that way too and O’Neil wasn’t supportive of the Knicks decision to let Jeremy Lin go because of all his marketing potential, according to a source. Sources also say O’Neil didn’t like the omnipresence of Isiah Thomas, who has yet to rejoin the franchise despite reports one year ago he was on the verge of accepting a position.

Howard is leaving the Mets after two decades in baseball to work for Dolan. The MSG Sports presidency used to be more involved in the basketball end when Steve Mills and Dave Checketts held it previously. Now, season ticket and suite sales, marketing, game presentation and community relations are its focal point.

“I am honored to be joining The Madison Square Garden Company, and particularly thrilled to have the privilege of leading MSG Sports,” Howard said in a statement. “There are very few organizations anywhere with the strength of MSG’s sports brands, and I look forward to utilizing my experience to ensure we build on MSG’s position as one of the world’s leading sports organizations. I would also like to thank the Mets’ ownership and organization for what has been an amazing professional experience in Flushing.”

Hank Ratner, the Garden CEO and Dolan’s righthand man, made the announcement in a release. According to the Knicks release, Howard served as executive vice president of business operations for the Mets, where he oversaw all business departments, including ticket sales & services, corporate sales & partnerships, marketing & communications, broadcasting, media relations, venue services, ballpark operations, guest experience and security.

“Dave has been one of New York’s premier sports executives for over two decades, and we are pleased he will be joining our Company to lead our sports business,” Ratner said in a release. “MSG Sports represents some of the most popular and enduring brands in the world, and we’re confident Dave’s vision and management skills will ensure we continue to earn the passionate loyalty of generations of fans, while developing strategic growth opportunities that help drive our business.”

The Knicks general manager is Glen Grunwald but he does not have the title of team president as Thomas and Walsh once did.
